The midrange of the data is 81 is your answer
Number patterns can be formed easily when we know the rule. In our case
The rule is n-4 ,
therefore , when n=1 then 1-4 = -3
n=2 then 2-4 = -2
n = 3 then 3-4 = -1
n = 4 then 4-4 = 0
n = 5 then 5-4 = 1
n= 6 then 6-4 = 2
Therefore we get a pattern -3,-2,-1,0,1,2,..............
hence in this case the difference between consecutive pairs is always 1
Answer:
A ≈ 26.42
Step-by-step explanation:
<em><u>The shape presented is a circle, and the formula for this is:</u></em>
A = π
<em><u>The "</u></em>
<em><u>," is the radius (2.9), so plug this into the formula:</u></em>
A = π
A = π8.41
A ≈ 26.42
If

denotes the sum of the first

terms of a geometric series with first term

and common ratio

, then





Using summation notation, you have

In this case, you have

,

, and

. So the value of the sum is

Rounded to the nearest whole number, the answer would be 3.
Original number 21.4709
Rounded to the nearest hundredth 21.471
